Title: Liquid surface detection
Inventor: ARAI SHOICHI
IPC: G01F23/22
Filed: 1991-02-01
Abstract: PURPOSE:To detect the surface of a liquid in a container even when the level moves at the time of heating the liquid by attaching temperature detecting means to the surface detecting points of the container and detecting the surface based on a change in temperature. CONSTITUTION:Temperature sensors 14a and 14b are attached to the surface of a container 11 at an interval in the vertical direction. When the container 11 is heated by means of a heating means 13 while the container 11 contains a liquid 12, the surface of the liquid moves as the temperature of the liquid rises and, when the liquid boils and evaporates, the surface drops down. The temperature detected by the sensor 14a attached to a level higher than that of the liquid surface is higher than one detected by the other sensor 14b attached to a level lower than that of the liquid surface. The temperature information given by the sensor 14b detecting the temperature of the liquid reaching a preset temperature is transmitted to a discriminating means 14 which in turn transmits an actuation signal to a liquid feeding pump 16. Then the pump 16 feeds an additional amount of liquid of a lower temperature to the container 11 from a liquid tank 17. Then the pump 16 is stopped in accordance with the preset temperature information given by the sensor 14b.
